Answered by The Community. Making the world better, one answer at a time. ovarian cycle is the cycle of ovary developed from follicles to yellow bodies, uterine lining is the cycle of building up and breaking down of the uterine lining(menstruation).
One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead. Another difference is sexual activity. In species with estrous cycles, females are generally only sexually active during the estrus phase of their cycle (see below for an explanation of the different phases in an estrous cycle).
